MACHINE FOR PRODUCING TYPE-BARS.

SPECIFICATION forming part of Letters Patent No. 650,934, dated une 5, 1900.

Application'filed October 21,1893. Serial No. 488,800- (No model.)

To all whom, it may concern:

Be it known that I, JosErHO. FOWLER, a citizen of the United States,residing at VVashington city, in the District of Columbia, have invented new and useful Improvements in Machines for Producing Type-Bars, of which the following is a specification.

This invention relates to that class of machines wherein types or dies representing characters or letters are forcedor driven into soft metal or other material to produce a line .of matrices from which a line of characters or words is cast and subsequently set up for printing purposes.

The chief object of the present invention is to provide an organized machine wherein circulating interchangeable cameo typeplates can be assembled or composed in a line; justified, and caused to indent a bar or body of soft metal or other material to produce a solid line of matrices from which a line of characters or Words maybe cast by casting mechanism inoperative connection with the other parts of the same machine in which the type-plates are assembled and subsequently distributed.

The invention also has for its object to provide a novel machine wherein the types of a justified line'o'f type-plates are caused to-enter material with a rolling action or rocker-like motion for making a solid line of matrices from which perfect type bars or lines of characters or words are cast.

To accomplish these and 0th erobjects which are hereinafter set forth, my invention involves the combinations of parts and the principles of operation hereinafter described and claimed, reference being made to the accompanying drawings, in which- Figurel is a side elevation of a portion of a machine constructed in accordance with my invention.

In the following description of my inven tion I will follow as nearly as possible the successive operation of the parts, explaining the construction, arrangement, and function of each element in the order in which its action contributes to the production of the final result.

In the accompanying drawings the reference-numeral 1 indicates the main frame of the machine, which rises from any suitable form of base 1, and from one member of which frame projects a. bracket 2, upon which is stepped a vertical shaft 3, forming the axis of the type-plate magazine 4. The base of the magazine is provided with a series of escapements,substantially as i n my Letters Patent No. 510,853, dated December 12, 1893, whereby the cameo type-plates lying in the radial cells are individually or separately released, the selections from said cells being made by the usual form of keyboard 5, having its keys connected by slender rods 6 to the slides 7 of the several escapements. As the cameo type-plates are released they pass by gravity into the series of cellchutes 8 beneath the magazine and are received by the revolving table 9, from which they are discharged in the order of their selection into a chute 10.

The cameo type-plates devised by me for the purpose of my present invention are each constructed, as shown in Figs. 12 and 13, of a body portion 12, provided at one end with a V-shaped notch 13, in which is formed the combination of points or teeth by which the type-plate is enabled to ride upon the distribution-bar of the magazine and be discharged into its appropriate cell. The body of the cameo type-plate is of a-thickness in proportion to the width of the letter or character thereon, and the laterally -projecting supporting lugs or shoulders 11 are preferably of uniform thickness. The end opposite the notched extremity is slightly convex or rounded off in the direction of the width of the typeplate, and projecting from the center of the convex face 15 is a cameo type 16 or other character used in printing.

Immediately beneath the lower end of the chute is journaled a carrier or holder for the type-plates, comprising two circular heads 17 and 18, mounted upon a shaft 19 and rigidly connected by an intermediate block 20, which is traversed by the shaft 19, upon each side of which the block extends to or nearly to the perimeters of the heads 17 and 18. This block may be formed in one piece with the heads of the carrier or holder; but I prefer to construct it separately and bolt the heads thereto, either construction giving a rigid connection to the parts composing the carrier. In the opposite transverse edges of the block 20 are formed line assembling or composing channels 21, havinga form which corresponds to the outline of the type-plate, the depth and arrangement of the channels being such that when a type-plate, is placed therein with its notched end in engagement with a grooved rib 22, Fig. 6, its convex end face will lie in the plane of the perimeters of the two heads 17 and 18, the convex end 15 being curved in an arc struck from the axis of the shaft 19. The parallel sides of the block are set in channels in the inner faces of the heads 17 and 18, Fig. 9, and the chan nels or spaces 21 are cut or formed to extend the full width of said block and are open along the ends thereof to expose the convex ends of the type-plates. The assemblingchannels are so arranged also that they are open, one upon the top and the other upon the bottom of the block, for a purpose presently to be explained. 3y this construction the lugs or shoulders 11 upon one edge of each type-plate willliesnbstantially flush with one surface of the block 20, as shown in Fig. 6.

The carrier or holder is so arranged that one of its heads, as 17, lies beneath and sub stantially in the same vertical plane with the chute 10, and in the outer face of this head is formed a curved or segmental channel or chute 23, which on ts the periphery of the head 17 substantially in the direction of a radius of the latter. The curved or segmental channel is curved to avoid the shaft 19, and one extremity cuts the periphery of the head at a point separated by an arc of about ninety degrees from the other extremity. The head 17 is provided with two of the channels 23, each of which is the counterpart of the other. The form of the channels in cross-section is such as to permit the body portion of the typeplate to enter the same, narrow and shallow channels 24; being provided to receive the lugs or shoulders 14 of the type-plates and allow their outer faces to be substantially flush with the outer surface of the head 17. Covering-plates 25 overlie the channels 24, thereby forming a curved chute in which the type-plates may slide freely in the direction of their length. When the shaft 19 is revolved and the carrier or holder turned until the entrance end of one of the chutes or channels 23 lies in a vertical line, as shown in Figs. 1 and 5, said chute will then form practically a continuation of the chute 10, so that the type-plates will pass freely from the latter into the channel or chute 23 and will traverse the latter by their own gravity and by the momentum they acquire until they arrive at the lower end of the channel 23, which coincides with one end of a line assembling or composing channel 2l, where each type-plate is arrested by a lip 20, which rises from the lower side of the chute 23 in such position that a slight lateral movement of the type-plate will cause it to enter the channel 21 in the end of the block 20 and engage its notched end with the angular rib This lateral displacement or movement of the type-plate is effected by an y suitable means such, for example, as a feeder composed of wipers 27, carried by a short shaft 28, supported in a bracket 29, mounted upon the outer face of the head 17. The wiper-shaft 28 is transverse to the chute 23 at the end of the latter and is provided with a frietion-pulley 30, which lies just below the end of the said chute when the latter is in position to receive the type-plates from the chute 10. The means for revolving the wiper-shaft will push the type-plates successively into a line-- assembling channel 21.

When the line of type-plates is completethat is to say, when the whole number representing a line or part of a line of printed mat-' ter, including the necessary spaces and characters, has been assembled in the channel 21- the series must be compressed in the direction of the length of the line in order to force the type-plates closely together and secure uniformity in the length of the successive lines. This may be accomplished by any suitable means; but, as here shown, I'provide for the purpose the line-compressor shown in detail in Fig. 11 and in operative position in Figs. 6, 7, 8, and 9. The line-compressor is composed of a bolt 31, having a wedge-shaped end 32, the two diverging faces of the latter lying in the longitudinal line of the channel 21. This bolt passes loosely through a slightlyelongated slot or opening 33 in the end of a bar 34, the other end of said bar being pivoted upon the flat face of the block 20 at a point between the two heads 17 and 18. A spring 35 has one end mounted upon the outer face of the bar 34, while the other extremity of said spring has a swivel or other similar connection with the head of the bolt, as best shown in Fig. 11. A second spring 36, attached at one end to the block 20, bears against the side of the bar 34 and normally throws the bar 34, against which its free end has bearing, over toward that side of the block 20 which is adjacent to the head 18, thereby carrying the bolt 31 to the corresponding end of the channel 21, where it lies during the time the said channel is being filled with type-plates and spacers. the bolt is drawn out of the channel 21 by raising it until a shoulder 37 upon its side abuts against the slotted end of the bar 34. The latter is then swung by hand toward the head 17, as seen in Fig.9, until its wedgeshaped point passes the type-plate which has last entered the channel 21, when the bolt is pressed downward by the spring 35 and if necessary by the hand of the operator, thereby driving the type-plates toward the head 18 and compressing the line to the required length, It may be mentioned at this point that compression within certain limits is rendered possible by the use of the elastic compressible spacer shown in Fig. .18.

The series of type-plates being com pressed longitudinally, it is next necessary to clamp the type-plates edgewise in order to bring the cameo type and other characters into accurate alinement. For this purpose I provide a clamp-jaw 38, mounted upon arms or supports 39, which are pivotally attached to an axis 40, arranged transversely to the block 20. The jaw 38 lies in the open side of the chan- When this operation is completed,

nel 21, and when the carrier or holder is in the position shown in Figs. 5 and 6 said jaw will lie directly beneath the lower edges of the type-plates as they enter and are moved forward in the channel 21. The arms or supports 39 are sustained in position by earns 41, underlying said arms and rigidly mounted upon a cam shaft 42. One end of this camshaft is earried through the head 17 of the carrier oi holder, and its projecting extremity is provided with a lug 43, in the path of which, as the carrier or holder turns with the shaft 19, is a lug 44, projecting from the inner face of the main frame 1 at such a point that it will engage said lug 43 almost immediately after the rotary movement of the carrier or holder is initiated. This en gagementis preserved until the cam-shaft 42 has been turned through part of a revolution, thereby driving the cams 41 against the arms 39 and forcing the clampjaw 38 against the edges of the type-plates. At the moment this is effected the lug 43 rides off the lug 44, leaving the jaw 38 in looking engagement.

In order to bring the faces of the cameo type into the same plane in case one or more should project slightly beyond the others, I provide a drum 45, carried by a shaft 45, which is journaled upon the main frame 1 at the front of the machine, said drum having half the diameter of the heads of the carrier. The periphery of said drum is tangent to the peripheral plane of the heads of the carrier. In said drum 45 may be seated a cushion 46, lying parallel with the axis of the drum and resting upon an elastic support 47, Fig. 4. The drum is so timed relatively to the carrier that the cushion 46 will roll upon and abut forcibly against the convex ends of the typeplates, the projecting type of the latter passing into a channel 48 in said cushion of suitable width. The cushion receives sufficient support from its elastic backing 47 to enable it to force any one or more of the type-plates which project more than others back intoexact alinement, thus bringing the entire series into such condition that a perfect impression can be made by the types in a bar of soft metal or other suitable material.

In the description thus far given I have explained the construction of one of the typeplate channels 21 and the mechanism cooperating therewith. Inasmuch as a similar channel is formed at the other end of the carrier-block 20, the said mechanism will be duplicated, with an alternately-opposite arrangement of the parts, in order that the second line assembling or composing channel 21 may by a half-revolution of the carrier or holder be brought into a position to receive the type-plates from the chute 10. The chute 23 is also duplicated upon the other side of the shaft 19, as shown in Fig. 5.

The line or series of type-plates being set up, compressed, and accurately alined, the next ensuing step in the order of operation is the formation of a type impression in the soft metal or other material which is to form the solid line of matrices from or by which the cast type-bar is produced. For this purpose I provide'a carrier or holder composed, as here shown, of a drum 49, rigidly mounted upon a shaft 50, journaled in the main frame 1 of the machine below the shaft 19. The drum 49 has a length equal to the outside length of the carrier or holder containing the assembling-channels, and its maximum diameter is equal to the diameter of the said carrier or holder. At each end of the greatest diameter of the drum is a projecting segment or portion 51, which extends in parallelism with the axis of the drum-shaftover the whole length of the drum, its width being equal to the maximum width of the typeplates, or nearly so, as shown in Fig. 12. Between these opposite segmental projections the surface of the drum is cut away, reducin g the opposite parts lying between said projections 51 to a less diameter.

In each of the opposite segmental projections 51 is formed a chamber 52, preferably of circular form and extending from end to end of the drum. The circular periphery of this chamber cuts the convex outer face of the projection, and thereby forms a longitudinal slot or opening having a width somewhat greater than that of the type-faces of the type-plates In the chamber 52 lies a matrix-blank or body of soft metal or other suitable material 53, lead or an alloy of lead or other alloy being employed. This bar or body corresponds in form and length to the chamber in which it lies, its size being such that it will fit somewhat loosely therein. A portion of the bar or body is exposed by the slot or opening in the convex face of the projection 51 and will project very slightly therefrom.

The drum-shaft 50 is revolved by gearing, which will be described hereinafter. It is timed to rotate in unison with the carrier or holder containing the assembling-channels, and as its maximum diameter is the same as that of the carrier-heads 17 and 18 the convex faces of the segmental projections 51 will have the same surface speed as the convex end faces 15 of the type-plates, and said faces will therefore roll one upon the other. During this movement the cameo types upon the ends 15 of the type-plates will be driven or forced in the soft metal of the bar 53, forming a series of intaglio impressions or indentations, which are the converse of the cameo letters or characters of the type-plates, and producing a solid line of matrices or a matrix-bar 54:, (shown in Fig. 1a,) from which a type-bar similar to that illustrated in Fig. 15 may be cast by the means and in the manner which I will now describe.

The pressure of the line of cameo types slightly swells or expands the bar-53, Fig. 12, andthns the bar is held sulliciently secure to prex'ent its accidental movement or displacement, but is not held so tightlyas to prevent its ready removal.

By rolling the line of cameo types against the bar or strip of soft metal or other material the types gradually enter the bar with a rolling or rocker-like motion, and in a typebar cast from or on the matrix-bar the edges of the letters or characters will stand higher than in type-bars produced from matrix-bars in which the letters or characters are sunk in a direct line, for which reason I am enabled to produce type-bars which attain the high perfection required in printing.

It is desirable to prevent the type-bar when formed from sticking to the matrix-bar, and this is especially the case in using a metal as plastic or soft as lead or the ordinary alloys of that metal. I have found that this result is best attained bysmoking the matrix-barusing, for example, a flame from aheavy hydrocarbon gas, whereby a thin film of unconsumed carbon is deposited upon the matrices of the matrix-bar by avery brief exposure to the action of the flame. I provide for this purpose a tube 55, arranged at a point in the revolution of the drum 49 beyond that where the type impression is made in the matrixbar and between the point of said impression and the mold where the type-bar is cast. This pipe is supplied from any suitable source with gas, which issues from small perforations, so formed that the gas-flame will impinge upon the matrix-bar during the halfrevolution of the drum 49 by which said matrix-bar is carried into a position where it will be presented to the mold.

The carrier or holder containing the typeplates and the carrier or holder for the soft metal make a half-revolution in unison at each action of the machine, and both are arrested when in the position shown in Fig. 4. While they remain at rest the type-bar or line of characters or words is cast, the line of typeplates by which the matrix-bar was formed is returned to and distributed in the cells of the magazine, a new line of type-plates is at the same time time set up in that one of the channels 21 opposite that from which the typeplates are being removed, and the soft-metal or matrix bar used in casting the preceding type-bar is driven out of the chamber 52 in the drum 49 and its place is supplied by an unimpressed bar. As these operations are all carried on concurrently during the period of inaction of the machine, I will next describe the means for casting the type-bar or line of characters or words and will then explain the mechanism for accomplishing the other mechanical operations referred to.

The mold used in this machine is preferably though not necessarily a four-part mold. It consists of a substantially-rectangular carrier or frame 56, having upon each of its four equal sides a mold 57 of suitable dimensions for the production of the body portion of a type-bar. The carrier-frame 56, carrying the molds 57, is formed in one piece with or rigidly attached to a clutch-section 58,which isloosely mounted upon a shaft 59, supported at one end in a bracket 60 on the main frame 1 of the machine and at the other end in a hori-. zontal beam 61, forming part of two standards 62, which rise from the base 1*. Rigid upon the shaft 59 is a clutch-section 63, between which and the clutch-section 58 is a spring 64, coiled upon the shaft inside of'the clutch-teeth. The tension of this spring constantly tends to force the mold-carrier 56 toward the drum 49, and as the shaft 59 is at a right angle with the drum-shaft 50 the rotating of these shafts will, by the engagementof the clutch-sections 58 and 63, rotate the mold carrier or frame and place one of the molds 57 into engagement with the projections 51, thus registering the mold with the opening in the said projection through which the matrix-bar is exposed. Beneath the shaft 59 is arranged a melting-pot 65, pivotally mounted upon a support or pivot and provided at its top with an arm 66, which projects upward, its end having a fork 67, which-lies in a race or channel 68 in the clutch-section 58. The arm 66 rises from that part of the top of the melting-pot which-lies next to the mold. Upon the opposite side of the top of said pot are placed two friction-rolls 69 and 70, the former being mounted in a frame 71, which is movable against the tension of a strong spring 72, and rigidly upon the shaft 59 is secured a camdisk 73, having two cam-faces 74 and 75, diametrically opposite each other, so formed that by the revolution of said cam-disk the melting-pot will be vibrated toward and from the mold-carrier 56. The vibration of the melting-pot operates the clutch-section 58 and causes it to engage or disengage the clutchsection 63. When the melting-pot swings in a direction away from the drum 49, the clutchsections engage and the mold-carrier makes a quarter-revolution. Within the pot 65 is arranged a piston 76, to which is attached a piston-rod 77, the upper end of which is pivot-ally connected to a hook 78, adapted to engage a lifter 79, rigidly secured upon the shaft 59 above the melting-pot. The latter is supplied with heat by any suitable means and is provided with an exit-channelSO, through which the molten type-metal flows under the pressure of the piston 76. The exit-channel 80 communicates with a horizontal mouth 81 of ordinary construction, which opens through a lip 82, the outer face of which is formed to iitaccurately upon the face of any one of the molds 57. The melting-pot in its relation to the four-part mold has such close resemblance to the same parts shown a1 described in my patent before alluded to that further description thereof is deemed unnecessary.

During the time the casting inechanisnris in action and while the other parts of the ma chine thus far described remain at rest the line of type-plates from which the preceding cast has been made must be removed from their channel 21 in the carrier or holder and returned to the magazine. For this purpose the head 18 of the carrier or holder is provided with curved channels 83, similar to, but alternating in their arrangement with, the curved channels 23 in the head 17, as shown by dotted lines in Fig. 6. These channels 83 register at one end with the ends of the channels 21, and at their other ends said channels 83 meet the periphery of the head 18 at points lying in the same longitudinal lines with the outer ends of the channels 23 at which the type-plates enter from the chute 10. The first type-plate which enters the channel 21 in the block 20 will lie when the series is complete in that end of the exit-channel 83 which coincides with the end of the channel 21, and it is for this reason desirable that this first plate introduced be a quad, or a mere blank without type, or a spacer. The line of typeplates will normally be pressed toward the end of the channel 83 by the impulse of the spring 36, acting upon the bar 34, which carries the line-compressing bolt 31. As the type-plates are successively withdrawn by way of the exit-channel 83 those remaining in the channel 21 will be moved by the linecompressor a step forward, thereby introducing the next type-plate in the series into said exit-channel 83.

Journaled in the upper part of the main frame 1 is a shaft 84, upon which is loosely mounted a sleeve 85, splined to said shaft, so that it may have a limited movement longitudinally while it is compelled to revolve in unison with the shaft 84. Forming part of or attached to said sleeve is a disk 86, having its plane of rotation parallel with that of the carrier-head 18. A spring 87, coiled on the shaft 84 and pressing against the end of the sleeve 85, holds the disk normally close to the outer face of said carrier-head, and from the adjacent flat face of the disk project pins or 'rigid fingers 88, which enter and sweep through the exit-channel 83 as the disk 86 revolves, the latter being so arranged-as to overlap the carrier-head 18 sufficiently for this purpose. The pins 88 are arranged at regular intervals, and they engage the type-plates successively, driving them upward in the exitchannel and into the lower end of a distribution-chute 89, Fig. 10. Immediately after entering this chute one of the lugs or shoulders 14 upon the type-plate is engaged by the spiral thread 90 of a lift-cylinder 91, which may be arranged in a casing 91. The cylinder 91 has a journal 92, stepped upon a bracket 93, projecting from one of the standards of the frame 1, Figs. 2 and 10. The disk 86 is timed with relation to the screw or lift cylinder 91 in such manner that the type-plates shall be engaged by thelower end of the spiral thread 90 at or nearly at the time the upper lug or shoulder 14 on each type-plate reaches the point where the thread can pass beneath it. The distribution-chute 89 is provided with a groove or I way 94, in which the lugs or shoulders 14, op-

posite those engaging the thread 90, have vertical movement. An opening crosses this groove or way to permit the pins 88 on the disk 86 to pass out of the chute after they ride off the lower ends of the matrixplates.

Vhenthe type-plate carrier or holder is to receive motion, it is necessary to remove the pins 88 laterally from the exit-channel S3, and this is accomplished by means of a lever 90, Figs. 2 and 3, having its fulcrum 97 upon a sleeve or collar, which is supported upon the shaft 19, between two ribs rigid thereon. One end of the lever is provided with a fork 9S,which engages a race or channel in the sleeve 85, and the opposite end of said lever is provided with a pin or stud 99, whichlies in acam-race 100, formed in a collar 101, rigidly mounted on the shaft 45. This cam-race is so formed and timed as to vibrate the lever 90 and move the sleeve 85 upon the shaft 81 against the pressure of the spring 87 far enough to wholly withdraw the pins 88 from the exit-channel 83 an instant before the carrier-head 1S begins to move. The cam-race 100 holds the sleeve and disk retracted until the halfrevolution of the carrier is completed, and, as the latter is arrested, the lever 96 swings in the opposite direction and the disk 86 returns to its normal position, with its pins 88 lying in and traversing the exit-channel S3 in the carrierhead 18.

During the time occupied by the operation last described the soft metal body or matrixbar last used in casting a type-bar is removed from its chamber in the drum 49 and a blank or unimpressed bar substituted in its place. This operation takes place upon that side of the drum which is removed by the whole length of its maximum diameter from the mold in which the casting is taking place and is effected by means of a bar 102, arranged to have longitudinal movement in brackets 103, projecting from the frame 1, and provided with a lug 104, by which the matrix-bar is pushed out of the chamber in the drum, and a feed-rod 105, attached to the bar 102 at one end, so as to lie parallel with but at a little distance from said bar, Figs. 2, 16, and 17. Upon one end of the bar 102 is an angular projection 100,which is engaged by an arm 107, carried by a shaft 108, journaled at one end 'in a bracket 109 on the main frame of the machine and at the other end in a bracket 110 upon one of the standards 62. The angular projection 100 is provided with a holding-face 112, and the extremity of the arm 107 has a prolonged eonvex face 113, Figs. 2 and 10, whereby when the bar 102 has been movet. longitudinally far enough to carry its lug 101 from end to end of the chamber containing the matrixbar and out of said chamber it will beheld and prevented from returning to place during the time occupied by the passage of the face 113 on the arm 107 over theholding-face 112 on the bar. This time is sufficient to permit the drum 49 to move far enough to carry the projection thereon which contains the chamber for the matrix bar out of the path of the lug 101. The bar is then free to return to its normal position, this movement being effected by a spring 114.

The feed-rod 105 is so located upon the bar 102 that its free or unattached end is separated from the lug 101 by an interval slightly in excess of the width of the drum 49. Above the feed-bar 102 is arranged a magazine or hopper 1.15,the closed lower end thereof hang ing close to that portion of the bar which lies between the lug 101 and the free end of the feed-rod 105 when the bar is in its normal position. The unattached end of the feedrod then lies just within a guide-thimble 11o, projecting from one side of the hopper, at its bottom. Upon the other side of the hopper is an aperture 117, Fig. 10, large enough to allow the passage of a single bar of soft metal or material. As said bar leaves the hopper its forward end follows closely after the lug 101 and enters the chamber in the drum 49 as the impressed matrix-bar leaves the same.

The bars of soft metal or other material are designed to be superimposed in the magazine or hopper 115 and are fed to the bottom of the hopper by gravity, so that the lowermost bar always lies in alinement with the feed-rod 105.

The machine is driven from a power-shaft 11.8, Figs. 1., 2, 3, and 4, having upon its end a bevel-gear 119, meshing with a bevel-gear on a vertical shaft 121. A spur-gear 22 on the latter meshes with an intermediate gear 123 of larger size, and the latter drives the lift-cylinder 91 through the medium of a spur-gear 124 upon its lower journal. The upper end of said lift-cylinder is provided with a bevel-gear 125, Fig. 3, which meshes with a similar gear 120 upon a worm-shaft 127, by which the distributing devices of the magazine are operated. The power-shaf t is connected by a belt 128 to a pulley 129 upon the end of the shaft 108. A grooved pulley 130 on the shaft 118 drives a belt 131, which is carried over guide-pulleys 1.32 to a pulley 133 upon the sleeve or hub 13-1, which forms part of the revolving table 9, beneath the magazine. A similar but smaller pulley 135 on the shaft 118 carries a belt 136, which drives a pulley 137 on the shaft of the pinwheel or disk 86. A large bevel-gear 138 upon the shaft 108 meshes with a similar gear 1 39 upon the shaft -15" and drives the drum 4:5, and upon the other end of the drum-shaft 45 is a spur-gear 1-t0, which meshes with a similar gear 111 upon the shaft 19 of the carrier, in which thbtype-plates are set up in line. The said spur-gear 111 on the shaft 19 meshes with and drives a spur-gear 142 of the same diameter on the shaft 50, which carries the impression-dru m 49.

The shaft 59, which actuates the casting mechanism, is driven from the shaft 108, which carries a bevel-gear 143, meshing with a like gear 144 upon a counter-shaft 145, the I shaft- 108, at the end which is belted to the power-shaft, is a sliding clutch-section 154, adapted to mesh with a clutch-section 155, which is rigid upon the shaft. On a bracket 156, forming part of one of the standards 62, is fulcrumed a lever 157, the forked end of which engages the race in the clutch-section 154. The lever is swung in a direction to disengage the clutch by means of a spring 158 and is provided with an arm 159, which projects beneath the shaft 108 and carries in its forked end a small roll 160, which rests when the shaft is revolving upon the periphery of a pulley 161, mounted on the shaft. This pulley is provided with a notch 160", Figs. 1 and 2, into which at the end of each revolution of the shaft the roll 160 drops, thereby allowing the spring 158 to swing the lever and disengage the clutch. The'operator then actuates the lever 157. to disengage the roll 160 from the notch 160 and throw the clutchsection 154 into engagement with clutch-section 155 to impart rotary motion to shaft 108.

In the present example of my invention the power-shaft 118 is designed to continuously operate the wiper-actuating devices, the table 9 of the magazine, the pin-disk 86, and liftcylinder 91; but all other operating devices, except, of course, the key mechanism, are controlled by the clutch-seetions 154 andl55.

It will be noted in Fig. 2 that the large bevel-gear driving the shaft 45 is mutilated or denuded of its teeth over abouthalf of its meshing circu m fercnce. The purpose of this construction is to enable the type-plate carrier and the parts cooperating therewith to perform their proper functions and then come to rest, the casting mechanism being then brought into action.
